Voltage Divider Calculator

The Voltage Divider refers to a device consisting of a resistor or series of resistors connected across a source of voltage and having one or more fixed or adjustable intermediate contacts where from any two terminals a desired reduced voltage may be obtained. A voltage / potential divider is a simple linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin) mainly used in physics. Generally, Vout is used as a reference voltage. Voltage divider is also called as potential divider.

Voltage divider referenced to ground is created by connecting two electrical impedances in series. Voltage dividers are used for adjusting the level of a signal, for bias of active devices in amplifiers, and for measurement of voltages. A Wheatstone bridge and a multimeter both include voltage dividers. A potentiometer is used as a variable voltage divider in the volume control of a radio.
